'Potential transformers' (US terminology) or 'voltage transformers' (UK terminology) are, together with 'current Transformers', collectively called 'instrument transformers', and are used to safely measure/monitor voltages and currents in high-voltage systems.
Potential transformers are used to reduce the voltage-level of a high-voltage circuit to a lower voltage which can then be read using an ordinary voltmeter; at the same time, it electrically-isolates the high-voltage system for the purpose of safety. Potential transformers, together with current transformers, can also be used to operate wattmeters, or to supply protective relays.

What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
How potential transformer works explain with circuit diagram?
A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
What are potential transformer?
potential transformer is that which transforms one range of voltage (potential difference ) to another range without changing frequency.AnswerA 'potential transformer' is the North American term for what, elsewhere, is called a 'voltage transformer'. It, together with a current transformer, belongs to a class of transformers known as 'instrument transformers'.Potential transformers are used to (1) reduce the value of a high-voltage supply to a lower value (often 120 V) so that it may be read by ordinary voltmeters, and (2) to electrically-isolate the voltmeter from the high-voltage source for the purpose of safety.In electricity substations, potential transformers are also used to provide an input to certain types of protective relay.
What is the ratio of a potential transformer from 4160V to 120V?
4160/120 = 34.666666 to 1
Advantages of current transformer?
A CT allows:heavy currents to be measured using conventional ammeters, andelectrically-isolates the ammeters from high-voltage primary circuits.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
What are the advantages of 3-phase transformer over 3 single-phase banks of transformers?
The main advantage is that the 'footprint' of a three-phase transformer is smaller than a transformer bank, and all connections are prewired which makes them easier and quicker to install and replace.
What is the full form of CT PT transformer?
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
How potential transformer works explain with circuit diagram?
A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
Can a distribution transformer be used as a potential transformer?
I'm not quite sure what you mean by a "potential transformer", but I look at it this way: The transformer isn't aware of the purpose to which you're putting it, so no matter what you call the function, the transformer continues to perform it ... transforming voltages and impedances in proportion to the turns ratio, and currents in proportion to its inverse.
What is potential pros?

What is the difference between capactive voltage transformer and potential transformer?
A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
